Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186078, here are decompositions:

  • 7 + 186071 = 186078
  • 29 + 186049 = 186078
  • 37 + 186041 = 186078
  • 41 + 186037 = 186078
  • 59 + 186019 = 186078
  • 71 + 186007 = 186078
  • 107 + 185971 = 186078
  • 127 + 185951 = 186078

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 186,078 and was likely granted around 1875.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 186078 first appears in π at position 744,714 of the decimal expansion (the 744,714ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
